  3. Techno meter
  4. Outside caliper
  5. Measuring scale
  6. Seam cutting saw
  7. Seam micrometer
  8. Thread (Nylon)
Audriance Seamer Machine

Working principle: The machine is semi automatic for closing oval, round, square, rectangular and other irregular shape cans. After filling the product the filled end is closed using the audriance seamer. In its working mechanism, the power from the electrical motor (i.e. driver pulley) is transmitted to the driven pulley by ‘V’ belt. The driven pulleys have a center shaft with two sets of bevel gears at the end. The combined rotation of bevel gears of driven pulley shaft and vertical shaft of seaming chuck transfers the power to the seaming head mechanism, which have two cams and two rollers; with brackets. The cams and small rollers guide seaming rollers to operate alternatively to complete the seam. Automatic seamer can seam about 10 to 15 cans per minute.

The machine essentially consists of the following parts.
  • Cast iron body
  • Electrical motor
  • Bevel gears
  • Cams and rollers
  • Seaming rollers
Procedure:
  • The condition of the machine is observed if necessary greasing, oiling; and cleaning should be done.
  • Keep the filled irregular can with lid over the lifter (base plate).
  • Switch on the machine
  • Press the foot pedal firmly.
  • Release the foot pedal after hearing the pin lock sound.
  • Switch off the machine after completion of the seam.
